libsql wal replica checkpoint #1714

Closed MarinPostma closed 2 months ago

MarinPostma commented 2 months ago

Implement replica checkpointing.

Replica can checkpoint segments up to the durable frame_no reported by the primary. The reason for that is that replica can always recover from the latest durable frame_no, avoid sync-from-scratch like with the previous version of the replication.

depends on #1711
